Location of Brake Controller Port Under Dash of 2015 Toyota Tundra with Factory Tow Package  


Where is the vehicles wiring harness plug located for the trailer brake controller on a 2015 Toyota Tundra with tow package?


Expert Reply:

The brake controller port for the 2015 Toyota Tundra is located behind the section of the dashboard with the tow/haul button. To reach the connector you will need to locate the notch in the access panel in the center of the dash near the driver's side. Using a trim panel puller like # ALL648544, carefully pry the panel out and undo the locking tabs to remove the panel. You will find the mating connector behind this portion of your dashboard.

The correct harness for your 2015 Tundra is part # 3031-P. Harness # 3040-P that you referenced is for older Tundra model years.
